the QAUDCTL system value contains *AUDLVL and either the QAUDLVL or QAUDLVL2

to display all of the audit journals:</span> <kbd class="userinput">DSPJRN QAUDJRN</kbd> <p>If you find an audit record of type IM, that means that IDS has flagged

|
a suspicious event. If no IM audit records display, IDS has not detected any
